To all who/n, 'it may oolmem.'

Be it known that I, GUY H. Boscone, a citizen of the United States, residing at lVenatchee, in the county ct Chelan and State of l fashington, have invented cert-ain neuY and useful. Improvements in Safety Devices for Automobiles, oi' which the follow# in@r is aspecitication.

liis invention relates to safety devices tor atoiiiobiles and more particularly to that class'thereof employed for the purpose.

ofoontmlling the operation of anyone of tl'iee'lctrig circuits, such as 'for instance the I spanking circuit@ the device being adapted' to heloclted' inirnosition when the circuit; is

rlhe invention has for one of its objects ,the provision ot an improved mechanism tor the purpose stated, comprising a moif'able switchinember constituting' a., member oit said circuit, and adapted to be automatically locked in its inoperative or open position,

vlphe invention has, furtharmena,` for its object the provision of an impiowelloclo controlled 'device which in itself may be made. of insulating material, but carries 'aM l 5*" l n v Contact maker adapted to. b'riclgc'a, pair of terminals which are elements of sani circuit.,-

= Further objects of the invention will hert` iniitfer appear and he particularly oehnecl in the claim.

, The inventionhas heen clearly illustrated in the accompanying drawings in which similar characters denote similar parts and which f f Fguisl is a front. View of myimprove-:l device, the casingheing out away@ ancl Fig.

`Referring to "tire, drawings, l0 clenotes a hase plate havingseurecl thereto an insulating block 11 which carries a pair of terminais or conta t points shown herein as resilienty blades V u2, EL between which 1the eurrent oi electricity is to he establishedl ,or inn terruptecl, :1s-the case may he. For purposes oi a general description of the operation, I

have shown in diagram one form oiE spark` ing circuit7 which eonn'irises a conductor le leading to a primaryI battery B, the other 'terminal 15 of which is conneetecl with one end of the primary-coiiv iii from which a conductor l? leads to tile Contact point .i3

' above mentioned. The secondary circuit; .comprisesthe outer Winding oan induction cuil i8' which is.' in circuit with the spark plugs? Sand' the timing device T, as. usual. .Fr-oni the foregoing it will be understood that operation is intended to occur in .this primary instead of the secondary circuit.

The means for connecting and disconnecting the terminals 12, 13, consists substantially oa shoe 19, made of metal and" cairielcl on the loiverend of a slide inemhei'ft which latter may be made of insulating ma; terial to prevent accidental grounding or 'other interfering with the proper operation, of the circuit. The slide 20 is guided with ils right hand emi against the inner :face ot a casing 21 Seated against the base plate and myclevice, and having a slot in its sifie through which projects a handle 23 for manipulating the slide. ln Fig. l the slide is shown in its cireuitclosing position, thel shoe 19 metallically connecting the'points l2 and i3, while in Fig.- 2 the slide is in its disconnecting position in which it is locked by the, sliding bolt 2e of a lock 25 which may heef any l "irecl construction and pref era. lj; oornprisesv means for automatically tl'iroiving said 'bolt into engagement or tonvard hthe slirle, as for' instance a spring 26. ilu-the other hand the locl such. that it requires a. key to retract the boltto release it from the slide, and more particularly from-the not-ch 27 thereof.

In thenresent yinstance the lett hantl face of the. slide has 'a series oft teeth 28 which are adapted not oniy to he engaged oy corresponding teeth 29 formed on the end of the holt, but lwhich are furthermore adapted to act pani faces and checks to prevent any accidental upward mifernent of the slide., `while on the other hand'thgy are not; sufiicient to prevent the pushed upward hy hami. Again, by this construction it Willhe seen that the slie in the present instance the switching A covering and inclosing the several parts of vslide troni being 'un he normally pushed upward. only, .the
